本文通过大量实测实验研究了火车、汽车在运行过程中引起的地面振动特性和衰减。采用数理统计的复合回归方法,探讨了振动的传播衰减规律,提出了地面垂直和水平振动衰减的经验公式。并和目前国内采用过的几种公式一起与实测结果对比,本文经验公式符合程度较好。文中还提供了防振距离的参考值。
In this paper, a large number of actual test experiments were conducted to study the ground vibration characteristics and attenuation caused by trains and automobiles during operation. Using the compound regression method of mathematical statistics, the law of propagation attenuation of vibration was discussed, and the empirical formulas for ground vertical and horizontal vibration attenuation were proposed. And with the current domestic formula used together with the measured results, the empirical formula of this article is in good agreement. The reference value of the vibration isolation distance is also provided in the text.
